[PATCH 0/3] z3fold: per-page spinlock and other smaller optimizations

[Vitaly Wool]

Coming is the patchset with the per-page spinlock as the main
modification, and two smaller dependent patches, one of which
removes build error when the z3fold header size exceeds the
size of a chunk, and the other puts non-compacted pages to the
end of the unbuddied list.
